Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Meat
Provides the base flavour and body of the broth as it simmers for hours.
Flour
Browned in butter and stirred in, it thickens the soup slightly.
Tomatoes
Add acidity and colour to the broth.
Potato
Softens during long simmering, adding body to the soup.

The step that matters

Boil slowly for 2 hours after adding the browned flour. Once the flour mixture is stirred in, the soup should simmer gently rather than boil hard. Vigorous boiling can break up the potato and cloud the broth, and steady low heat lets the flour thicken smoothly without lumps.
